Field evaluation of plastic film liners for petroleum storage areas in the Mackenzie Delta / D.E. Thornton, Environmental Emergency Branch, Environmental Protection Service ; P. Blackall, Environmental... : En46-3/76-13E-PDF

"An inspection tour was made of seven petroleum storage areas in the Mackenzie Delta area to study the use of artificial liners employed at each site to enhance the spill retention capabilities of these tank lots. Of the six types of membranes viewed by the inspection party, polyurethane (20 mil.) prestressed laminated polyethylene, and fibre-reinforced polyurethane appeared to show promise as lining materials. It was noted that bedding preparation is important if the membrane has a low puncture resistance, and also that an adequate thickness of protective overburden is desirable, as exposed membranes invariably become damaged. It was concluded that carefully chosen and properly installed plastic membranes can be effective and economical for artificially enhancing the spill retention properties of petroleum storage areas in the Arctic. In particular, plastic membranes appear applicable for buried installation in permanent tank lots during the initial foundation construction, but not suited for improving existing installations"--Abstract, page i.
